Description
Technical field
The present invention relates to a kind of centralized central air-conditioning ventilating system.
Background technology
As everyone knows, centralized central air-conditioning ventilating system comprises hybrid filtering section, wind outlet section and ventilation shaft, and fillter section comprises primary efficient filter screen and the medium air filtration net that is used for blocks dust, and ventilation shaft comprises return air pipeline and air-out pipeline, after the air-treatment, deliver to each air-conditioned room by ventilation shaft.Yet this ventilating system is easy to generate all contaminations, and human body is worked the mischief, and its main cause has:
1, after porous heat-barrier material suctions such as the thermal insulation layer in the ventilation shaft such as glass fibre or neoprene are made moist, can grow microorganism, become bacterial reproduction ground.It is particularly like this when it is in cooler pan or humidifier downside;
2, the thick residue of imitating after filtering of dirt in fresh wind port and the return air duct and process in the hole of deposited thermal insulation layer, becomes pollution sources in also can be accumulated in;
3, adopt mastic coating tubes inwall, then volatile organic matter can discharge from dope layer, becomes the pollution sources of organic gas;
4, inner as coagulate in water pond, filter, humidifier and so on darkness and the wet environment at ventilation shaft, microbial reproduction is swift and violent, and the air-flow air supply duct enters each room.
Therefore, at above-mentioned situation, adopted various air disinfection and purification means in centralized central air-conditioning ventilating system, at present, modal mode is as follows:
1. class is filtered in charcoal absorption.Such mainly is that airborne bacterium and volatile organic matter are adsorbed with fresh air.This method advantage is an easy operating, and shortcoming is all harmful substances all can not be adsorbed and active carbon is easy to saturated and secondary pollution, and can only suppress bacterium can not kill bacteria.
2. anion generator class.Such mainly is to produce negative oxygen ion by the negative high voltage electric field, with airborne cation neutralization, airborne floating dust is increased to fall, fall with the bacterium on the floating dust simultaneously, to reach the effect of fresh air, this method has certain bactericidal action but is not really complete, to the not effect of organic contact scar gas.
3. high-pressure electrostatic control of dust class.The principle of such sterilization method is that positive and negative electrode is set, and when air passes through, dust and the various particle that carries disease germs is adsorbed onto on the electrode, to reach the effect that purifies sterilization.This method is depositing dust and sterilization to a certain extent, but for not effect of toxic and harmful (as aldehydes, benzene class, TVOC etc.).Poor to micro organism purifying effect.Also want regular cleaning electrode plate or change collection body, in case produce secondary pollution.And bigger problem is that volume is big, and the cost height is safeguarded inconvenient.
4. ultra violet lamp excites net to carry powder attitude photocatalyst class.Such device adopts the powder attitude photocatalyst on the ultra violet lamp wire netting, produces factor groups such as hydroxyl ion, hydroxyl ion and decomposes organic gas, kill bacteria.But reaction speed is too slow, under certain wind speed, and not effect.When pollutant levels were big, clean-up effect was too poor.And the cost of wire netting own is bigger.
5. smell oxygen and purify the sterilization method class.Such is for sterilization, purifying organic and remove the peculiar smell effect all clearly, but the excessive concentration of smelling oxygen can produce infringement to human body, also cause certain infringement to air-conditioning duct simultaneously.
6. ultraviolet sterilization.Ultraviolet disinfection lamp only is fit to the sterilization to unmanned stationary body, and the sterilization of air is subjected to the restriction of uitraviolet intensity and air velocity, distance, and limitation is very big.
In sum, existing centralized central air-conditioning ventilating system with air disinfection and purification function can not satisfy the demand of society, therefore, need improve existing centralized central air-conditioning ventilating system.
